Frequently Asked Questions
It controls the amount of CV affecting the pulse width, allowing for finer adjustments and preventing signal overload.
No, it's designed for triangular, sawtooth, or sine wave inputs to generate a rectangular wave; a square wave input would just pass through unchanged.
While usable, it's on the lower end; you might need a gain stage before your VCA to ensure sufficient signal strength.
